|Common Name||Mentawai Treeshrew|
|Range||Indonesian Mentawai islands of Sipora, North and South Pagai.|
The Golden-bellied treeshrew (Tupaia chrysogaster), also known as the Mentawai treeshrew, is a species of treeshrew in the Tupaiidae family. It is endemic to the Indonesian Mentawai islands of Sipora, North and South Pagai. It lives in forests, and is considered endangered due to habitat loss since the islands' forests are continuously logged.
The American zoologist Gerrit Smith Miller first described a golden-bellied treeshrew from North Pagai Island that was part of a zoological collection obtained by the United States National Museum. He considered it a distinct species as this type specimen differed from the common treeshrew by larger teeth and skull, darker colored fur on the back and a more coarsely grizzled tail.
